Is it possible to display a wpf window without an icon in the title bar?

Question

As we all know, if the icon for a wpf window is undefined then the default icon is displayed. I want to display a window without any icon in the title bar. I realise that I could use a blank image, however this would cause the text in the title bar to be offset to the right.

Does anyone know of a way to completely remove the icon?

(I tried searching for a similar question but couldn't find anything.)

Simple, add this code to your window:

[DllImport("user32.dll")]
static extern uint GetWindowLong(IntPtr hWnd, int nIndex);

[DllImport("user32.dll")]
static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);

private const int GWL_STYLE = -16;

private const uint WS_SYSMENU = 0x80000;

protected override void OnSourceInitialized(EventArgs e)
{
    IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(this).Handle;
    SetWindowLong(hwnd, GWL_STYLE,
        GetWindowLong(hwnd, GWL_STYLE) & (0xFFFFFFFF ^ WS_SYSMENU));

    base.OnSourceInitialized(e);
}
